Application filed August 2, 1917. Serial No. 184,040.

To all whom it may concern:

Be it known that I, EMIL BUBLrrz, a subject of the Emperor of Germany, but have made application for citizenship of the United States, residing at Irvington, in the county of Essex and State of New J ersey, have invented certain new and useful Improvements in Combined Antiratt-ling Safety-Lock and Ventilating Devices for Windows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates, generally, to improvements in anti-rattling and tightening devices for windows; and, the present invention has reference, more particularly, to a novel means adapted to be attached to and cooperating with the sashes of a window, to provide a combined anti-rattling and safety device, applicable to windows of various construction, the device serving also as a combined safety-lock and ventilating means, to permit either orboth of the window sashes to be respectively raised or lowered to their full extent, or to permit a limited movement of either or both of the window sashes for ventilating purposes, and to lock the window sashes, in that case, against further movement, so that it will be impos sible for a person to enter from the outside of the window, or to manipulate the combined anti-rattling means and safety-attachment from the outside in the endeavor to raise or lower the window sashes a distance sufficient to permit entrance into the room through the window.

The inventlon, therefore, has for its principal object to provide a novel, simple and cheaply constructed, as well as efliciently operating attachment or device for the purposes herein-above stated, which provides a combined anti-rattling and wind-proof safety-lock, as well as a ventilating means, comprising but a very few parts, and being readily attached in its operative position with relation to the respective window sashes, without interference to the lowering or raising of the window sashes to their fullest extent, or to a limited degree, either at the top or bottom, at both ends of the window, for ventilation.

Other objects of the present invention not at this time more particularly enumerated will be clearly understood from the following detailed description of the present invention.

With the various objects of the present invention in view, the said invention consists, primarily, in the combined anti-rattling and wind-proof safety-lock and ventilating means for windows hereinafter set forth; and, the invention consists, furthermore, in the novel arrangements and combi- Figure 1 is an inner face view of a win- I,

dow frame and its window sashes, showing the upper sash locked by means of the mechanism embodying the principles of the present invention in a partly lowered position; and Fig. 2 is a horizontal sectional Y representation of the same, said section being represented as taken on line 22 in said Fig. 1, and said view being made on an enlarged scale.

Figs. 3 and l are transverse vertical sectional representations of the window frame and window sashes, showing in the respective views, and in operative cooperation with the upper and lower window sashes, and in its locked and unlockedrelation with the window sashes, the combined anti-rattling and wind-proof safety lock and ventilating means.

Fig. 5 is a detail view, in side elevation,

of a portion of a window-frame 'and'one of j the controlling vor operating levers of the combined anti rattling and wind proof safety-lock and ventilating means provided with an auxiliary locking means for retaining the lever in its position against m'ovement, when the combined safety-lock and ventilating means has been operated.

: Similar characters of, reference are employed in the said above described views, to indicate corresponding parts.

lower'meeting-rail 10-ofthe upper sash o 'and-theupp'er meeting rail 11 ofthe'lower Referring .now to'the said drawings, the reference-character 1 indicates any usual construction of window-frame in which are slidably disposed betweentheusual .stiles 2 and 3 and the stop-beads 4:, the upper window'sash-o and the lower Window sash 6, the said stiles and beads being secured in any suitable and usual, manner upon the faces of side-members 7 of the window frame. As shown, the vertically disposed stiles 3 are channeled or grooved, as at 8, and the stopbeads are similarly channeled-or, grooved,

as at 9. Likewise, at the central portions of theside-members 7, in'alinement with-the sash6,*when both sashes are closed the said side-members 7 are provided with thehori- -zontally disposed and rearwardly extending 'channelsor grooves 12. Pivotally mounted uponsuitably-disposed pivots 1 3, as nails, screws, plns, or the like, are oscillatory levers or arms 14, each arm thus being m'ovably disposedin' a channel or groove 12 and-havinga portion extending from said channel or groove '12 and being-provided with asu1t- *able finger-piece, as 15. Extending from each 1 lever or arm 1 1 is a pivot-pin 16 upon wh ch is I looselymounted a v downwardly extending ibindin'g' or presser-plate 17, said plates being 'movably dlsposed 1n the chan- 'nfels orgrooves'9 of the beads a andhaving right-angled portions or flanges '18 adapted to be brought into frictional binding or pressingengagement withthe faces oi' the -vertical rails 19 oithe lower window sash in the manner and forthe purpose-s hereinafter more fully stated,

Asshown iniFigs. 3' and 4 of the drawings, the "said binding or-presser-plates 17 are also provided withangularly disposed elongated 'slots-or'openingaas 20, into which extend correspondingly "placed pins or screws 21 with which the side-members 7 of the Windew-frame are provided. Each lever or arm 14 is also provided with another pivot- -pin, as 22, upon which is alsodooslyinounted an upwardly extending binding or presserfplate 23, said plates bei'ng movably disposed-in thechannels or groove-s 8' of the stiles 3 and hELVlIlQW1gllh-filigled portions or 'llangesfle adapted to be brought into -frictional binding or pressing engagement with thevefrtic'al rails "25 ofthe upper window s'ash in the 'mamie'r and 'for the purposes hereinaifter more fully stated.

gXs-indicated :in dotted outline in Figs. '3 and dot th'e drawings, the said binding or press'er 'plates' 23 'are 'a-lso provided with anzgularly "disposed elongated slots or openings, a s 26, into which extend correspondingly placed pins or :screws 27 "with which the side-members 7- ofthewindow-fr'ame are "also provided.

When the several devices and parts of the herein-before described combined safetylock and ventilating means are in their relative positions-indicated in Figs. 2 and 3 of the drawings, it will be seen from an inspection of said figures, that the binding or pressing portions or flanges 18 and 24 of the respective'plates 17 and 23 areout of frictional retaining contact with the respective side-rails l9 and 25 of the lower and upper window-sashes, so that either or both of said sashes can be moved up or down to be brought intotheir opened or closed positions within the window frame, as will be evident. When, however, the said arms'or levers 14 are 'movedfrom their positions indicated in Fig. 3 of the drawings to thepositions shown in'Fig, el, then the fulcrumal arrangement of said arms or levers 1 1 upon the pivot pins 13 will cause theplates 17 to slideupwardly upon the pins -21, thereby bringing their binding or pressing portions or flanges 18 into firm holding or retainingengagement with the innerfaces of the side-rails19 of the lower "window sash andpressing the. outer face-portions of said side-rails into frictionalretaini ng engagement with the-corresponding face-portions of the stiles 2. 'Simultaneously, the said arms or levers ll will cause the plates 23 to slide downwardly upon the pins 27, thereby bringing their binding orpressing portions or flanges 2st intO firm holding or retaining engagement with theouterifaces of the side-rails 25 of the upper window sash and pressing the inner faceportions of said side-rails into frictional holding or retaining engagement with the corresponding face-portions of the stiles 2. Thus, both window sasheswhether previously opened, or whetherin their closed positions will be securely held or locked the'stil'es 2, and the joint between the'meetin'g {rails 10 and 11 of the lower and-upper window sashes will be brought into uch "tightcontact, so'that a perfect and positively 1 wind-proof Window is the result.

To guard against'aocidental movement of 'the arms or levers 14 when brought into the positions indicated in Fig. a of the drawings, an auxiliary locking device or means such as is shown in Fig. 5 may be employed, although any other suitable locking means may be used, if desired.

The locking means here represented in said Fig. 5 consists, essentially, of an arrangement of racks 28, attached by means of pins or screws 29 upon the inwardly eX posed face-portions of the beads 4, each arm or lever 14; being provided near its fingerpiece 15 with a pivot-pin 30. Engagement of suitable holding dogs, as 31, which are pivotally mounted upon said pins 30, with the teeth of the racks 28 is caused by an arrangement of suitable springs, as 32, as will be evident.

The arrangement of these parts permits of the upward movements of the arms or levers 14, and positively retains said arms or levers against accidental movement from their raised positions.

To disengage the holding dogs from the teeth of the racks, when it is desired to lower the said arms or levers 14:, each dog 31 has a projection or extension, as 33, which serves as a fingerpiece for the withdrawal of the holding dogs from the racks, simultaneously with lowering operations of the said arms or levers 14 by means of their fingerpieces 15.

I am aware that some changes may be made in the general arrangements and combinations of the several parts, as well as in the details of the construction of the said parts, without departing from the scope of the present invention, as set forth in the foregoing specification and as defined in the clauses of the claim which are appended thereto. Hence, I do not limit my invention to the exact arrangements and combinations of the parts as described in the said specification, nor do I confine myself to the exact details of the construction of the said arts as illustrated in the accompanying rawings.

I claim 1. A combined anti-rattling safety-lock and ventilating device for windows comprising a pair of vertically placed presser plates having angularly disposed elongated openings, pins projecting from a side-member of a window-frame, said pins extending into said openings whereby said plates are movably disposed upon said side-member of the window-frame, each plate having a flange adapted to be brought into frictional retaining engagement with a window sash to provide a binding action of the window sash in the window-frame so as to prevent rattling, and means connected with said plates for actuating said plates simultaneously in opposite directions.

'2. A combined anti-rattling safety-lock and ventilating device for windows comprising a pair of vertically placed presserplates having angularly disposed elongated openings, pins projecting from a side-member of a window-frame, said pins extending into said openings whereby'said plates are movably disposed upon said side-member of the window-frame, each plate having a flange adapted to be brought into frictional retaining engagement with a window sash to provide a binding action of the window sash in the window-frame so as to prevent rattling. and an operating lever pivotally mounted upon said side-member of the win- (low-frame and also pivotally connected with each plate for actuating said plates simultaneously in opposite directions.

In testimony that I claim the invention set forth above I have hereunto set my hand this 27th day of July, 1917.
